2 Claims. (Cl. 29-219) This invention relates generally to heavy dutyinternal combustion motors and particularly to a valve lifter for dieselmotors.

The main object of this invention is to facilitate the lifting of heavyduty motor valves for repair purposes.

The second object is to make the removal of the valves a one man job,which one man can perform in less time than is ordinarily required fortwo men and without danger to the fingers of the operator.

The third object is to so construct the lifter that it can be used on awide variety of styles and types of diesel motors.

I accomplish these and other objects in the manner set forth in thefollowing specification as illustrated in the accompanying drawing, inwhich:

Figure 1 is a side elevation showing a portion of the device and aportion of a valve head broken away in section.

Fig. 2 is a section taken along the line 22 in Fig. 1.

Fig. 3 is a. section taken along the line 33 in Fig. 1.

Fig. 4 is a section taken along the line 44 in Fig. 2.

Fig. 5 is a perspective of the adapter shown in Fig. 1.

Referring in detail to the drawing, there is shown a valve head in whichis formed a valve seat 11 for a disc valve 12 whose stem 13 extendsthrough a bushing 14 in the head 10. On the stem 13 above the face 15 isa compression spring 16,"it being understood that the valve '12 andassociated parts are in multiple to correspond to the number of valvesto be lifted.

It will be understood that each stem 13 is provided with a reduced endportion 17 for the conventional washer 18 which normally occupies arecess 19 in the spring cap 20 into which extends the upper end of aspring 16.

Referring particularly to my invention, same will be seen to include abase plate 21 having a boss 22 on its under side through which extends ahold down bolt 23 by means of which the plate 21 can be rigidly mountedon the face 15 by mounting the bolt 23 in the tapped hole 24 in the face15.

On the plate 21 is mounted an adapter (Fig. 5) comprised of a plate 25having a tapped hole 26 for a clamping bolt 27 whose head is on theunderside of the plate 21.

On the plate 25 is a tubular socket 28 adapted to receive a standard 29which may be secured to the socket 28 by a pin 30, preferably secured bya cotter pin 31. Various holes 32 may be provided along the standard 29to provide a quick change in the setting beyond the range of theturnbuckle unit which will be described.

On the standard 29 is slidably mounted the cross slide 33 provided withrollers 34 to reduce friction. Attached to the slide 33 is a pusherplate 35 having holes 36 formed therein to receive the washers 18 of agiven group of valves. The top side of each hole 36 is provided with acountersink 37 to facilitate the removal of the washer 18.

The plate 35 is attached to the slide 33 by means of Patented June 14,1960 a bolt 38 which is tapped into the plate 35. Attached to the slide33, by means of a pin 39, is the lower rod 40 of a turnbuckle whose nut41 is joined to the upper rod 42 which is joined by a pin 43 to anoverthrow lever 44 whose end 45 is joined by a pin 46 to an ear 47formed on the upper end of the standard 29. The lever 54 has a socket 48into which may be inserted a handle 49.

The operation of the lifter is as follows: Assuming that the parts arein the position shown in Fig. 1 and it is desired to remove the valves12, all that is needed is to depress the lever 49 which will cause theplate 35 to be depressed as shown in Fig. 4 and cause the lever 49itself to be held in a locked depressed position, in which the valvelock washer 18 may be inserted or removed with a minimum of efiort ordanger.

Obviously, to release the lifter, it is only necessary to raise thehandle 49 past its locking center and restore it to the position shownin Fig. 1.

I claim:

1. A valve spring compressor for overhead valves comprising an elongatedhorizontal base plate, a boss on the under side of one end of said baseplate, a hold down bolt through said base plate and boss, a verticalsocket on the top side of the opposite endof said base plate, an uprightstandard in said socket, said socket and standard having transverseapertures receiving a pin to secure the standard in the socket, a slideprojecting from one side of said standard parallel with and overhangingsaid base plate, rollers on said slide engaging opposite sides of saidstandard, a pusher plate on said slide adapted to engage valve springson opposite sides of said slide, a hand lever hinged to said one side ofsaid standard and extending over said slide, and a push rod having finelength adjustment pivotally connected between said slide and hand leverto depress said pusher plate.

2. A valve spring compressor for depressing a group of springs ofoverhead valves projecting upwardly from a valve head comprising anelongated base plate having a hold-down bolt in one end thereof forsecuring the base plate in horizontal position against the top of thevalve head between said springs, a vertical upright standard secured onthe opposite end of said base plate, a horizontal slide extending oversaid base plate from one side of said standard, rollers on said slideengaging opposite sides of said standard to provide for verticalmovement of said slide on said standard, a pusher plate on said slideadapted to engage the upper ends of said valve springs on opposite sidesof said slide, a hand lever hinged to said one side of said standard andextending over said slide, and a push rod having turnbuckle lengthadjustment pivotally connected between said slide and hand lever todepress said pusher plate, said push rod and hand lever forming aself-locking toggle joint when said hand lever is depressed.
